Abstract The present study investigated the effect of monoglycerol-stearate and carnauba wax (0.5% w/v) containing Shirazi thyme essential oil (TEO: 150 ppm) on the physical (moisture content, water activity, firmness and color), microbial (total counts, yeast and mold) and sensory properties of raisin during 12 weeks storage at room-temperature. Sensory quality of samples was investigated by the fuzzy-ranking method. The results show that there was a significant difference in moisture content and water activity between uncoated and coated samples (p
